APPARATUS FQBC LEABING TNTERI'II' DIATE CHUTES' Application 'filcd March 23, 1922. Serial No. 548,196;

To all '20 7mm it may concern Be it known that I, Josnrrr Mmnnonn, a citizen or the United States, and a resident of Paia Maui Territory oi' Hawaii, have invented certain .new and useful Improvements in Apparatus for Clearing Intermediate Feed Chutes, of which the following is aspecification.

h iy'invention relates to impr vements in 1o cane sugar mills and it consists in the constructions, combinationsand mode of operation herein described and claimed.

An object of the invention is to provide an intermediate chute to be disposed beportionsyone of which is hinged at the summit so that .it may be tilted for the purpose of clearing the chute.

Other. objects and advantages will appear in the following specification, reference being had to the accompanying drawings, in Wl1iCl1Z I Fig. 1 is a side elevation showing the hinged part of the intermediate chute raised into the dotted line position to illustrate the clearing action,

Fig. 2 is a plan view, and r Fig. 3 is a detail section on line 33 of Fig. 2.

This invention is an improvement on the intermediate chute of the cane sugar mill disclosed in my co-pending application for Letters Patent filed July 7, 1920, Serial No. 394,456. Briefly described, the old structure comprises a chute generally designated 13. The chute extends between adjacent macerating mills 11 and 12. It has oppositely inclined portions which meet at the summit 9.

The receiving portion 15 is of less inclination than the discharge portion let. The receiving portion 15 has scrapers 22 which enthe discharge sides of the macerating rolls 11 so as to clean the surfaces of adhering material.

Bars 23 carry the scrapers 22. These bars also carry levers which are adjustable by means of the turnbuckle rods 21. The scrapers are set in respect to. the inacerating rolls 11 by adjusting the turnbuckles.

The improvement comprises standards 31 which support the chute portion 1 1 and to which the chute portion 15 is hinged at 32. The standards carry a sheave 33 near the upper end of one. The strand of a wire tween adjacent mills, including two inclined rope 3st passes over this sheave and is fas tened at the upper end oi the other standard.

The other end of the wire rope 34. is tastoned to a drum 35 which is wide enough to accommodate a brake band This band is actuated by a lever 37. The drum has a gear 38 which is turned by means of the crank 39 and pinion at). A pawl and ratchet e1 checks the drum 35 from counter rotation when the chute portion 15 has been elevated into the dotted line position in Fig. 1.

The bight of the rope passes through sheaves &2 which are suitably aiiixed to the sides of thechute portion 15 near the forward end. The standards 1 are braced by tie rods The upper free ends or the sides of the chute 15 are overlapped by the sides of the chute 1%. This arrangement prevents leakage while the bagasse passes upwardly and toward the right in the chute portion 15.

The purpose oi the improvement is obvious. There are times when the sugar mills must be shut down, and at such times it is desirable and necessary to clear the intermediate'chute 13. This is efiectually done by elevating the receiving side 15 in the dotted line position so that all materials adhering to the bottoms and sides (and which would otherwise run back into the mill 11) may gravitate into the discharge side 1 1 where it will run into the mill 12 but from which it can be readily removed.

Fig. 3 plainly shows the arrangement carried out at the hinge 32. This hinge comprises a rod on which the chute portions are supported. The inner chute 15 is fastened to the rod as shown. The outer chute 1% has bearing on the same rod, so that the rod may easily turn in respect to the chute 14 which is fixed. The rod in turn has bearing on the end standards.

I claim 1. In combination with adjacent sugar cane mills, a sectional chute for conveying bagasse from one to the other, and means for tilting one section in respect to the other to cause the bagasse to gravitate toward the. other section and clear the chute when shutting down the mills.

2. A chute for conveying bagasse from one mill to another comprising a fixed part, and an associated part which is movable in respect to the fixed part to cause matit) '- able portion on the-pivotand in respect to i mills and 1n respect to the companion fixed 4.
